Purpose

The driver program pzdrive2_ABglobal.
This example illustrates how to use pzgssvx_ABglobal to solve
systems repeatedly with the same sparsity pattern of matrix A.
In this case, the column permutation vector ScalePermstruct->perm_c is
computed once.  The following data structures will be reused in the
subsequent call to pzgssvx_ABglobal:
       ScalePermstruct : perm_c
       LUstruct        : etree
On an IBM SP, the program may be run by typing:
   poe pzdrive2_ABglobal -r <proc rows>=""> -c <proc columns>=""> <input_matrix> -procs
